  • Why should we test Water TDS before and in use of MBR? Dec 07, 2023
    Why is it important to test water TDS? In order to understand feedwater quality fully and assess the possibility of membrane fouling and blocking caused by contaminants in water, we suggest you to monitor some critical parameters before and in use. TDS, NTU, TSS, SDI, TOC, DOC, COD, BOD, Oil and Grease, Fe and Mn, Calcium and Magnesium, Conductivity pH and silicon dioxide, etc are commonly tested before the design of membrane module. Among those parameters, TDS tests are one of the most common water quality measurements used by professionals and homeowners alike. This is because TDS in water is naturally occurring, tough to remove, and easy to test.   What is TDS? Total dissolved solids (TDS) is a measure of the dissolved combined content of all inorganic and organic substances present in a liquid in molecular, ionized, or micro-granular (colloidal sol) suspended form. TDS are often measured in parts per million (ppm). TDS in water can be measured using a digital meter.   Why should we contact local professional water quality testing institutes? TDS meters measure the conductivity of the water in parts-per-million(ppm), which is equivalent to measuring the mass of contaminants present per liter of water(mg/L). TDS is a nonselective measurement. It does not differentiate between the salts dissolved in your well water and the naturally occurring mineral content, like magnesium and sodium. If your TDS levels are above 600, or even in the 1000s, it is a huge indicator that there is a wildly problematic level of dissolved material present in your water. A reading between 300 and 500 is considered acceptable, but it is difficult to distinguish which dissolved materials are in your water from a TDS reading alone. To determine whether any dangerous TDS are in your water or not, you must rely on other test. The EPA considers TDS to be a secondary drinking water contaminant. Secondary drinking water contaminants pose no health risks and though there are suggested optimal levels of these contaminants, the EPA does not enforce these standards. Instead, these are considered to be primarily cosmetic, aesthetic, and technical inconveniences. For example, acidic water is not dangerous to consume, but it is extremely corrosive and destroys household plumbing. Hard water similarly does not run the risk of making you and your family sick, but it will wreak havoc on your water heaters and household appliances. High levels of iron can turn your water a bright unattractive orange color, but this does not mean that drinking this water will cause illness.   A Feedwater Quality Analysis Report for your Reference: Analysis Institute :                                                                      Analyst:                                  Water  Source Overview :                                                                 Date:                                 Conductivity:                                pH:                     Temperature of water sample: oC                          Type of source water: □  underground water/deep well water        □  lake water/reservoir water       □  river water □  sea water                                                  □  municipal water                         □  municipal sewage □  industrial sewage                                      □  others                                                                                                                              Temperature (deg. C.) pH          TDS (mg/L)                    TSS(mg/L)                  Turbidity (NTU)                      Oil and grease (mg/L)             COD (mg/L)       BOD5  (mg/L) TOC (mg/L)                    DOC (mg/L)                   Fe (mg/L)                  Mn (mg/L)                    Others: design minimun maximum remark                                                                                                     Pretreatment technology:                                                                                                              chemical:  □  flocculant                        □  coagulant aids                        □  bactericide Pretreatment device name:       Pretreatment situation: _________________________________________________________
